SAW SET.

Application filed December 26, 1922. Serial No. 608,889.

To all whom t may concern.' f

Be it known that I, ADoLrl-I MILLER, a citizen of the United States, and resident of the city of Kirkwood, county of StLouis, and State of Missouri, have invented certain new and useful Improvements in Saw Sets, of which the following is a specification, containing a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in saw sets vand has for its primary object a saw set whereby it is possible to'so adjust the plunger that it will only contact with the tooth being set.

A further object is tofconstruct a sawset which has a plunger capable of being turned on its longitudinal'axis so that during the process of setting a saw, it will come in contact with one tooth only, consequently it is possible to get thesame amount of set on both sides of the saw. Heretofore, unless a person was expert in setting saws there was a great danger of destroying the set on one side of the saw while theother side was being set, so that the teeth would project farther on one face than on the other, by my device, an inexperienced person is enabled to set a saw as accurately as an expert.

In the drawings:

Fig. 1 is a top plan view of a saw set embodying my improvement;

Fig. 2 is a side elevation of the same;

Fig. 3 is a longitudinal vertical section of the forward part of the saw set, the handles being broken away;

Fig. 4 is an enlarged front end elevation e0 of the plunger;

Fig. 5 is a diagrammatic view showing the position of the plunger of the present type of saw set relative to the saw teeth and Fig. 6 is a diagrammatic view showing my adjustable plunger in position.

In the construction of my device I em-v ploy a handle 7 which is preferably U shaped in cross section and which is shapedV so as to form a convenient grip for the fin gers, this handle'isprovided on its forward end with a yoke 8, the yoke` 8 is substantially elliptical and has its end walls provided with'a V shaped recess 9, the handle 7 is provided with spaced apart upwardly il projecting ears 10 between which is secured a handle 11, this handle is pivotally mountedron a rivet or stud 12, the handle 11 is provided with a projection 13 which con-y tacts with the endlof the plunger 15, the forward end 16 of the plunger is cutaway so as to leave the end 16 substantially wedge shaped, the remainder of the plunger is cyj lindrical; surrounding the plunger is acoil spring 17 which bears against a washer 18, this washer is held in position bymeans 'of a` pin l19, the pin 19 is designed-to extend upwardly and is for the purpose, not only` of holding the spring 17l in operable position, but also to allow the. plunger 15 to be rotated on its longitudinal axis, and in order to hold the plunger in fixed position I employ a shield 2O which is providedwith Y,

longitudinally extending slots 21 'through which the pin 19 projects, the shield. 2O is provided with arms 22 by means of which itjis pivotally secured tothe handle 7 by means of the rivet 12, the handle 7 is also provided with agauge 23 which is for the purpose of regulating the amount of set given to the teeth, this gauge is adjustable and is heldin position by means of a thumbscrew 24; mounted in the yoke 8 is an anvil 25, which anvil is verticallyv adjustable by `means of the thumb-nut 26; the purpose of adjusting this `anvil vertically is to take care of various sizes of saw teeth, by lowering the anvil, a coarse tooth is taken care of, while by raising it, the desired adjust-V ment is obtained for the finer teeth.

The operation of my device is as follows: After the gauge 23 and anvil26 have been properly adjusted, the pin 19 is turned so as to rotate the plunger 15 onits longitudinal axis either to the right or left depending in which direction the teeth are being set, of course, it is necessary before this rotation can be accomplished, to swing the' lshield upward so as to clear the pin, when the plunger has been set the shield 2O is moved downward so that the pin projects through one of the slots, the saw set is now worked in the ordinary manner, that is, by pressing on the handle 11, but due to the rotation of the plunger 15, it has assumed the position shown in Fig. 6 so that it contacts with one'tooth onlyand with no part of any other tooth; afterthe one side of the saw has been set, the shield 20 is again lifted upward and the pin turnedy to the opposite side, when the former operation is repeated. Y

In the event that it is desired to set saws havingMteeth,suehras areueonnnonly fo und in buokssatvs, the pin i19 isiplaeedinhaLvertical position.

The reason that it is iessentialvto .rotate the plunger 15 is illustrate`d'in`Fig. 5, since it is necessary to apply pressure to the point of the tooth and Where the plunger is not adjustable, the plunger twill :press against the heel of the tooth immediately in front df thatfbeing set, this hasfav tendency either tofstraightenout any setting previously inipartedtofthatitootlrand also toiputa kink in the -sa-W Wliioli'-1nakes it wirtually y'impossible `to fsaw Y on 'a straight line and also causes the saavto hang or dnag in=the out, neeessitatingthe. expenditurer of unneeessary physie-alilahor. Of` eoursewith the V shaped tooththe point'being equifdistant from the base onfbothsides, it islnet ineeessarythat theplunger'fbe @rotated in either direction.

vdelaying f'fully described my invention, what I- 'claim' is-:-
